latex2mathml converter generates non-standard menclose tags

[arnoudbuzing]

https://developer.mozilla.org/en-US/docs/Web/MathML/Element/menclose

This:

import latex2mathml.converter

latex_input = "\\boxed{\\dfrac{-7 + \\sqrt{61}}{2}} and \\boxed{\\dfrac{-7 - \\sqrt{61}}{2}}"
mathml_output = latex2mathml.converter.convert(latex_input)

mathml_output

generates output with the non-standard tag:

<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow><menclose notation="box"><mrow><mstyle displaystyle="true" scriptlevel="0"><mfrac><mrow><mo>&#x02212;</mo><mn>7</mn><mo>&#x0002B;</mo><msqrt><mrow><mn>61</mn></mrow></msqrt></mrow><mrow><mn>2</mn></mrow></mfrac></mstyle></mrow></menclose><mi>a</mi><mi>n</mi><mi>d</mi><menclose notation="box"><mrow><mstyle displaystyle="true" scriptlevel="0"><mfrac><mrow><mo>&#x02212;</mo><mn>7</mn><mo>&#x02212;</mo><msqrt><mrow><mn>61</mn></mrow></msqrt></mrow><mrow><mn>2</mn></mrow></mfrac></mstyle></mrow></menclose></mrow></math>

Is there a way around this?

@arnoudbuzing Thanks for opening a ticket. Not really sure. I based most conversions from outputs of other tools such as MathJax which also outputs menclose for the above. If you know any good reference for proper conversion, that would be nice.
